1 Claim.

This invention relates broadly to windows, more particularly to casement windows and to means for securing such windows at the desired position of adjustment.

An object of the present invention is to provide a device through the medium of which a casement window may be suitably hinged in position and at the same time secured at a desired position of adjustment; an essential feature of the present invention being the provision of hinge means whereby th window may be swung to a complete open position substantially parallel to the outside surface of the wall of the building for maximum ventilation.

The above and other numerous objects and advantages of the invention will be apparent from a consideration of the following description taken in connection with the accompanying drawings wherein- Figure 1 is a fragmentary levational View illustrating the application of the invention.

Figures 2, 3 and 5 are detail sectional views taken substantially on the lines 2-2, 3-3 and 5-5 of Figure 1.

Figure 4 is a detail sectional view taken substantially on the line 4-4 of Figure 3, and

Figure 6 is a fragmentary elevational View showing the handl of the adjustment device as positioned interiorly of the building.

Referring more in detail to the drawings, it will be seen that 5 indicates a more or less conventional casement window sash, while the reference numeral 6 indicates the frame for the window.

In accordance with the present invention there is provided for the window 5 upper and lower hinges I and B respectively.

The upper hinge I includes an elongated hinge arm 9 secured to the frame 4 and extending outwardly therefrom, together with an elongated hinge arm I secured to an upper corner of the sash frame of the window 5, and at the outer end thereof the hinge arms 9 and II] are apertured to accommodate a hinge bolt I I.

The hinge 8 includes an elongated hinge arm I2 secured to a lower corner of the sash frame of the window and extending outwardly therefrom substantially on the diagonal, together with :a hinge arm I3 that is secured to and extends :from the window frame 6 at a right angle to the :frame.

At the outer ends thereof the arms I2 and I3 :are formed to provide bearings for a combination hinge bolt and shaft I4.

Further in accordance with the present invention there is provided a gear case I5 that is disposed at the outer side of the frame 6 and through which the lower portion of the combination hinge bolt and shaft I4 extends as shown in Figure 4.

A portion of the combination hinge bolt and shaft I4 arranged within the casing I5 is squared or otherwise rendered not circular as at I6 to conformably fit the bore of the hub of a gear IT with which is in constant mesh a worm I8 also accommodated within the casing I5 and mounted on one end of a shaft I9.

The shaft I9 extends transversely through the window sill 2|], there being provided for housing that portion of the shaft extending between the sill 20 and the gear case I5 a tubular housing 2I as best shown in Figure 2.

On the end of the shaft terminating within the interior of the building there is provided an integral crank 22.

From the above it will be apparent that by turning the crank 22, shaft I9 will be caused to rotate, and this rotative movement of the shaft is transmitted through the gearing I! and I8 to the combination shaft and hinge pin I4 thus causing, in an obvious manner, the window sash 5 to swing on its hinges in a horizontal plane to opened and closed positions.

As clearly suggested in Figure 3 the sash 5 may be swung to a complete open position to substantially parallel the wall of the building so that when in this position the sash will offer substantially no resistance to the inflow and exhaust of air through the window opening thus providing for complete and substantially maximum ventilation.

It will also be appreciated that through the medium of this mechanism the window sash may be held in intermediate position as found desirable; and that also the arrangement will in no wise interfere with the use of window blinds, screens, or the like.

It is thought that a clear understanding of the construction, operation, utility and advantages of an invention of this character will be had without a more detailed description.

Having thus described the invention what is claimed as new is:

In combination with a pair of elongated and outwardly extending hinge members for connecting a sash to a frame with one member connected with the frame and the other to the sash, a casing connected to the underside of the outer end of the hinge member which is connected with the frame, a pivot pin passing through the outer end of the two hinge members and connected with the hinge member carried by the sash and said pivot pin having a non-circular part located in the casing, a worm wheel connected with said non-circular part located in the casing, a shaft passing through a part of the frame and into the casing, a worm gear on the outer end of the shaft and located in the casing and meshing with the worm gear, a handle connected with the inner end of the shaft for rotating the same to cause the worm gearing to open or close the sash, a sleeve extending from the frame to the casing and through which the shaft passes, the said hinge member carried by the sash being arranged at an angle from the sash to the pivot pin.
